Unintentional Asphyxial Deaths in Adolescence Autoerotic Asphyxia and Asphyxial Games as Part of the Same Syndrome Andrés Rodríguez Zorro Acknowledgments: My sincere thanks to Professor Peter Vanezis for his commitment and dedication as a teacher in each of his presentations during the program, for sharing his experience and knowledge in the practice of autopsies and for his guidance in addressing the subject of this dissertation. It is an honor to have been a pupil of the highest authority in the field of forensic pathology in the UK. Thanks to the entire faculty of the Masters program and at Barts and the London School of Medicine and Dentistry; to life for giving me a second chance and allowing me to grow personally, academically and professionally during my year at fascinating London.

Unintentional Asphyxial Deaths in Adolescence Autoerotic Asphyxia and Asphyxial Games as Part of the Same Syndrome Andrés Rodríguez Zorro 1.0 ABSTRACT OBJECTIVES: Unintentional asphyxia among preadolescents and adolescents by compression of the neck and other means of inducing hypoxia / anoxia in order to get exhilarating effects are not new or uncommon behaviors and can lead to death by accident. Medical science has described autoerotic asphyxiation and more recently asphyxial games “choking games” as different entities. This study addresses both behaviors to understand the characteristics of how these practices are presented as well as the risks factors to them in order to determine if there are substantial differences between the two practices, or if instead they are related behaviors. Accurate knowledge of these behaviors based on scientific evidence will facilitate the understanding of the etiology and manifested features and facilitate the implementation of preventive measures to avoid such deaths. METHODS : A retrospective study of fatal cases published in recognized scientific journal articles of both autoerotic asphyxiation and choking game behaviors in the adolescent population was made. Articles on sociology, psychoanalysis and psychiatry as well as studies previously published case series and epidemiological studies to assess student population etiological factors and risk factors associated with behaviors were included in this review. Features of both behaviors, such as prevalence, age distribution, gender, type of asphyxia and place of occurrence are presented. RESULTS : The results are consistent in all variables analyzed for both behaviors. Most practitioners are men. Cases of both behaviors in preadolescence show a tendency to increase with age. The most frequent type of asphyxia identified was hanging conducted in private quarters. Psychiatric and psychoanalytic literature identifies common elements between male castration complex, failed oral psychosexual development and the practice of asphyxia in its integration with sociological theories of risk and confrontation ordeal in adolescence. The review of epidemiological studies reveals common elements in the development of both practices in terms of risk factors. CONCLUSIONS: The evidence suggests a link between both practices and allows to theorize that they are part of the same syndrome. Integrating psychoanalytic and sociological concepts as well as the risk factors suggests a linear sequential model of development in four stages: childhood syndrome rope, asphyxial games associated to masturbation, Adolescent autoerotic asphyxia and Adult Autoerotic Asphyxia fetishist / bondage Syndrome. Death is explained in each of the stages as failed physiological and emotional adaptation mechanisms. It is important to disseminate knowledge of these practices among health professionals and further studies should be carried out in regarding deaths by hanging in children and adolescents.

Unintentional Asphyxial Deaths in Adolescence Autoerotic Asphyxia and Asphyxial Games as Part of the Same Syndrome Andrés Rodríguez Zorro 2.0 METHOD OF UNDERTAKING THE LITERATURE SEARCH The analyses were based on an extensive search of electronic databases available through the Queen Mary University of London and British Library. The databases included both: medical and psychological publications: PubMed (Medline), PsychINFO, PsycARTICLES, PsycCRITIQUES, PsycEXTRA and the Psychology and behavioral Sciences Collection. The terms used for the search were: choking game, asphyxial games, self strangulation games, sexual asphyxia, autoerotic asphyxia, autoerotic asphyxiation, autoerotic fatalities, autoerotic death, hypoxiphilia, asphyxiophilia, sexual asphyxia syndrome, adolescent sexual asphyxia, adolescent asphyxia, unintentional asphyxia, voluntary asphyxia. All published studies and articles available were reviewed and the papers considered for the revision were: 1. Studies of series of fatal cases of autoerotic asphyxia in general population 2. Case reports of voluntary asphyxia deaths in late infants, preadolescents and adolescents (age between 7 and 19 years). 3. Studies of both: asphyxial games and autoerotic asphyxia in preadolescents and adolescents. Other autoerotic deaths (non asphyxial) were excluded. 4. Peer reviewed journals and articles 5. Publications in English, French or Spanish. Other languages were excluded. 6. Articles published prior to 1990 were excluded to ensure that current and salient data were presented (with the exception of some early influential papers). Relevant forensic pathology, psychology, sociology, epidemiology and psychoanalytic literature related with autoerotic asphyxia, asphyxial games and hypoxiphilia were all considered.

Unintentional Asphyxial Deaths in Adolescence Autoerotic Asphyxia and Asphyxial Games as Part of the Same Syndrome Andrés Rodríguez Zorro 3.0 INTRODUCTION 3.1 DEFINITION OF AUTOEROTIC ASPHYXIA Autoerotic deaths have been defined by Byard 1, as “accidental deaths occurring during individual, usually solitary, sexual activity in which a device, apparatus, or prop used to enhance the sexual stimulation of the deceased in some way caused unintentional death”. Typical methods of autoerotic activity leading to death are mostly asphyxia maneuvers: hanging, ligature strangulation, plastic bag, chemical substances, or a combination of these. Other asphyxia methods includes: chest compression, positional asphyxia and drowning. Atypical methods include electrocution, overdressing/body wrapping, foreign-body insertion, and other miscellaneous methods 2. Autoerotic asphyxiation syndrome was described by Resnik 3 in 1973 as "repetitive erotic hanging", also known as asphyxiophilia or hypoxyphilia. It is a paraphilia in which sexual arousal and achieving orgasm depend on self-strangulation
